Digital video surveillance
First Claim
1. A system for use with one or more video surveillance cameras comprising:
- a video database module wherein a database entry includes at least one sensor condition defining an alarm state for each camera;
an alarm condition module receiving one or more sensor signals from one or more sensors associated with a camera and retrieving the at least one sensor condition defining an alarm state for the camera;
wherein the alarm condition module outputs an alarm signal if the alarm condition module determines that the one or more sensor signals meets the one or more sensor conditions.

Abstract
A control system for use with one or more video surveillance cameras forming a video surveillance system. The control system includes a video database module wherein a database entry includes at least one sensor condition defining an alarm state for each camera. Additionally, there is an alarm condition module that receives one or more sensor signals from one or more sensors associated with a camera and retrieves the sensor condition defining an alarm state for the camera. The alarm condition module outputs an alarm signal if the alarm condition module determines that the one or more sensor signals meets the one or more sensor conditions. The control system is modular and may be distributed in a network environment. The control system also monitors the network bandwidth and can adjust the throughput of digital data representing the digital images in order to avoid any bandwidth limitations.

9. A method for operating a digital video surveillance system, the method comprising:
-
providing to a computer one or more sensor signals associated with a camera;
accessing from a database, a record for the camera wherein the record includes an alarm condition for the camera;
ascertaining if the alarm condition has been met using the sensor signals; and
if the alarm condition has been met, outputting an alarm signal. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A control system operative with one or more cameras and one or more sensors to form a video surveillance system, the control system receiving a request for images from one or more of the cameras over a network having an associated bandwidth, the control system comprising:
-
a display module for receiving the request from the network and providing to the network an output of the requested images from the one or more cameras;
wherein the display module monitors available network bandwidth and adjusts the output to the network based on the available network bandwidth. - View Dependent Claims (20, 21, 22, 23, 34)

24. A computer program product having computer code thereon for operation on a computer system, the computer code controlling a digital video surveillance system, the computer code comprising:
-
computer code for receiving one or more sensor signals associated with a camera;
computer code for accessing from a database a record for the camera wherein the record includes an alarm condition for the camera; and
computer code for ascertaining if the alarm condition has been met using the sensor signals and if the alarm condition has been met, outputting an alarm signal. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33)

35. A method for controlling a video surveillance system operating in a network having an associated bandwidth, the method comprising:
-
receiving a request originating from a location associated with a user interface in the network for transmission of images from one or more of a plurality of cameras from the video surveillance system;
obtaining the images from the one or more cameras wherein the images are composed of digital data;
determining if the digital data for the images to be transmitted exceeds an available bandwidth of the network;
reducing the digital data until the digital data no longer exceeds the available bandwidth of the network; and
transmitting the images to the location associated with the user interface. - View Dependent Claims (36, 37)
